I am working on mainlining this SoC again which I started in Summer 
2013.

This adds initial support for Broadcom network SoC from the BCM5301X 
and BCM470X line.

The vendor BSP also uses BCM5301X for this SoC, so I just toke that.

I haven't found a better solution than the abort handler for the memory fault.

I do not have any documentation, only the vendor source code published 
by Asus and Netgear to conform with the GPL, it would be nice to get 
some documentation for this Soc like this
https://www.broadcom.com/collateral/pg/440X-PG02-R.pdf
for the Broadcom BCM440X Ethernet controller.

With some additional patches I got Ethernet working with ~250 MBit/s.

A bootlog can be found here:

First three patches Acked-by: Arnd Bergmann [off-list ref], with my
one comment addressed by removing the timer_init function.

About the fourth patch, I'd still hope we can find a less invasive
workaround than to trap all external imprecise data aborts.
